Red Sea Seawater Refractometer - Accurate Salinity Measure d-d Concentration: 5 mL (1 capful)The Red Sea Refractometer R12018 is an advanced instrument designed specifically for measuring the absolute salinity of seawater at a standard reef aquarium temperature of 25C (77F). This precision device eliminates the need for seawater or temperature compensation factors, as it is calibrated precisely for natural seawater (NSW). Unlike traditional refractometers that are typically calibrated for brine (NaCl solutions), the Red Sea Refractometer
